Description

Twin Needles are designed for small elongated die applications (≤0.7mmx1.0mm) to reduce the propensity of tilted dies during the ejection process. For elongated dies, single tip needles with one point of contact will create a pivot action and cause the die to see-saw when being ejected.

Our line of Twin Needles are designed and manufactured to the most stringent tolerances. Both twin ejector tips are controlled with a common datum for maximum flatness during the ejection process. Quad Needles come with 0.7mm diameter and will fit into most standard needle holders.

Oricus manufactures a wide range of Twin Needles to fit various die sizes. Pitch-to-Pitch positions start from 0.30mm x 0.30mm and tip radiuses start from R0.015mm. We can customize Twin Needles with additional features according to your die size, process or application requirements.

Features

  • Better for small elongated dies compared to Single Needle or Quad Needles
  • Comes in Cemented Carbide, HSS and Stainless Steel materials
  • For Pierce-Through or small die applications, special sub-micron grade Cemented Carbide materials are available
  • Needle Pitch-to-Pitch, radius and diameter are fully customizable according to your requirements

Benefits

  • Twin Needle’s 2 point contact with even distribution of force during ejection for elongated dies offers better balance as compared to Quad Needles
  • One-time set up of Quad Needles eliminates needle offset issues with multiple single tip needles
  • Multiple Twin Needles can be implemented for larger elongated dies (≥1.0mm x 3.0mm) to reduce contact pressure per ejection point while improving overall ejection stability

Material Information

Each and every material selected for use in our products go through a stringent Selection, Development and Assessment process. In-house developed compounds are developed with the latest innovations in material technology and feature formulations that are designed specially for use in the Semiconductor industry. For externally procured materials, each material goes through a rigorous Quality Assurance and Performance Assessment programme before being qualified for use in our products.
